To [ZZZ 1071 0172 2 25 may concern: 1

Be it known thatI, SAM MoRrLIN. a citizen of Ukraine, residing at Bolivar, in the county of lVestmoreland and State of Pennsylvania, have invented certain new and useful Improvements in Rail Joints, of which the following is a specification.

This invention relates to new and useful improvements in rail joints.

An important object of the invention is to provide a rail joint of the scarf type wherein the ends of the rails are counterparts which will permit the replacement of worn out or damaged rails.

A further object of the invention is to construct a rail joint of the above mentioned typ wherein the overlapping ends will be interlocked to prevent separation of the same should a portion of the securing bolts become loose orremoved. y

A further object of the invention is to construct a rail joint so that the adjacent rail ends may be securely joined without employing the usual fish-plate.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,

Figure 1 is a side elevational view of a rail joint embodying the invention,

Figure 2 is a top plan view ofthe rail joint, having a portion cut away to display the interlocking means employed to connect the rail ends,

Figure 3 is a horizontal sectional view taken on line III-III of Fig. 1.

Figure 4 is a fragmentary perspective view showing one part of the connection means'carried by one rail end, and

Figure 5 is a fregmentary perspective view showing the securing means carried'by the adjacent rail end.

Referring more in detail to the accompany drawing, there is shown a rail joint of the scarf type wherein the adjacent ends of the rails A and B are identical in construction and consist of a base portion 1, a web portion 2 and a head or ball 3.

As stated heretofore, the adjacent ends of the rail sections A and B are identical in construction so that a detailed description of one rail end is deemed sufiicient to make the invention clearly understood. The base 1,

-web:2 and head or ball 3 are cutaway on a vertical central plane to provideone scarf 580131011. There is provided at the inner end of the cutaway portion a transversely exthe rail head or ball 3 that is constructed tending dove-tail-shaped recess 4 formed in with an inclined end wall 5. The outer end i of the rail head or ball 3is provided with a transversely extending dovetail-shaped lug 6 that is provided with an inclined outer face 7 to correspond with the inclined wall 5 extending on an obtuse angle to the axis of the M11 as described. It is intended to lllustrate in the perspective views shown in Figs. 5 and 6, the inclination of the wall 5 and outer face 7, forming parts of the transversely extending dove-tailed-shaped lug 6 and recess 4, on an obtuse angle to the axis of the rail, as set forth in Fig. 2.

The scarf portions 2 of the webs 2 are provided with alined openings 8 that are adapted to receive the securing bolts 9 and nuts 10 for preventing lateral shifting of the rail ends, the said openings being of slightly greater diameter than the diameter of the threaded portion of the bolt.

It will be apparent, in connecting the, respective rail ends that the overlapping portions will be moved horizontally towards each other to position the transversely extending dove-taiLshaped lug 6 within the transversely positioned dovetail-shaped recess 1, thereby securely holding the rails against longitudinal separation of the same. The inclined end 7 of the dovetail-shaped lug 6, when engaging the inclined surface 5 of the dove-tail-shaped recess 4, will further aid in securely holding the ends of the rail by a wedging action when the nuts 10 are tightly drawn up on the bolts 9, the difference in diameter between the openings 8 and bolts. 9 allowing for slight, relative, longitudinal movement between the rails being connected. It is to be understood that the form of my invention herewith shown and described is to be taken as the preferred example of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

Having thus described the invention, I

claim:

1. In a device of the character described, a base portion, a head portion, a web portion connecting said base and head, the said said base, web, and head portions being cutaway on a central vertical plane, the said head portion having a transversely extend ing dove-tail-shaped recess, provided with an inclined end wall, formed at the inner end of the cutaway portion and a transversely extending dove-tail-shaped lug, provided with an inclined outer face, formed at the outer end of the cutaway portion.

In testimony whereof I affix my signature.

SAM MORYLIN.
